Gibraltar 74363540 Double Threaded Stud 1/2-13 9 in

Product Description

The GIBRALTAR 74363540 is an equal double threaded stud with a 1/2-13 thread size and a 9-inch overall length. It is machined from alloy steel and finished in black oxide for corrosion resistance in demanding environments. The stud carries a Class 2A thread fit, indicating a standard external thread tolerance suitable for general fastening applications. Electricians, HVAC installers, plumbers, and mechanical contractors use double threaded studs to create secure, removable connections in equipment mounting, structural assemblies, and pipe-support systems. This part ships as a single piece per package with a minimum order quantity of 2.

Equal double threaded studs like the 74363540 are used wherever a through-bolt is not practical and both ends of the fastener must accept a nut. Typical applications include equipment base mounting, vibration-isolation brackets, boiler and heat exchanger tie-rods, and conduit-support strut assemblies. The black oxide alloy steel construction suits indoor and light-duty sheltered outdoor installations where moderate corrosion resistance is required.

Key Features

• Equal thread length on both ends for symmetrical nut engagement
• 1/2-13 UNC thread size for compatibility with standard SAE hex nuts and hardware
• Class 2A thread fit — standard tolerance for general mechanical and structural fastening
• Alloy steel construction for high tensile strength relative to carbon steel studs
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 9-inch overall length suits longer reach mounting and tie-rod applications

Compatibility

Designed for use with standard 1/2-13 UNC nuts, washers, and threaded couplings in mechanical, HVAC, plumbing, and electrical trade applications.

Installation Notes

Installation is performed by licensed mechanical, HVAC, or electrical tradespeople as part of equipment mounting or structural fastening tasks. Power down or de-energize any equipment before installing studs in proximity to live electrical components. Use a stud driver or two-nut method to drive the stud into a tapped hole without damaging the thread. Verify that mating nuts and threaded inserts conform to the 1/2-13 UNC thread standard before assembly.
